基于云边协同的交直流混联电网线路过负荷协调控制方法
Coordinated control method based on cloud-edge coordination for AC/DC hybrid power grid line overload
摘要
Abstract
Aiming at the problem that many factors affect the formation of AC/DC hybrid power grid line overload,which makes it difficult to capture the line operation characteristics and achieve accurate control,a coordinated overload control method based on cloud-edge collaboration was proposed.The mathematical model of overload state was established,and the decoupling algorithm was used to solve the incremental values of power parameters under different degrees of overload and conduct feature extraction further.By employing it as the cloud computing reference value of cloud-edge collaborative algorithm,the coordinated control parameters that simultaneously meet the requirements of optimal power,minimum energy consumption and load shedding were obtained to achieve coordinated control.The experimental data prove that the cloud-edge collaborative method can accurately detect all nodes out of the blind area under the constraint of blind area,without missing detection.The changes in node power of photovoltaic and wind power output are significantly higher than those of normal nodes,showing the better overload control effect over all three types of nodes.关键词
